Product details
Overview
SMBJ6.0CHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 58.3 A peak current - protecting sensitive MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMBJ6.0CHE3/5B datasheet, SMBJ6.0CHE3/5B pinout, SMBJ6.0CHE3/5B application, or SMBJ6.0CHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<800 µA at VWM), while the SMB package provides MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility.
Designed for single-pulse and repetitive transient suppression, SMBJ6.0CHE3/5B delivers 600 W peak power handling per JEDEC-standard 10/1000 µs waveform at TA = 25 °C, with thermal derating above 25 °C per Fig. 2 and junction-to-ambient thermal resistance of 100 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin below system rail voltage. |
| VBR @ IT = 10 mA | 6.67–7.37 V - Verified breakdown range ensuring reliable turn-on during overvoltage events without premature conduction. |
| VC @ IPPM = 58.3 A | ≤10.3 V - Clamped voltage under full 600 W surge; defines maximum stress imposed on protected downstream circuitry. |
| PPPM | 600 W - Peak pulse power rating with 10/1000 µs waveform; determines survivability against lightning-induced surges and inductive switching spikes. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); supports robustness during fault conditions in DC power paths. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive and high-temperature industrial environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with cathode band marking; compatible with J-STD-002 solderability and JESD22-B102 whisker testing. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side connection | Connected to ground or lower-potential node in unidirectional clamp configuration; forms return path during surge conduction. |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 5 V rail or sensor input); avalanche breakdown occurs here when VIN exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS, and infotainment power rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0AHE3/5B | No AEC-Q101 qualification; commercial-grade only; identical electrical specs and SMB package. | Not approved for automotive use; acceptable for consumer or industrial non-safety-critical designs. | Select SMBJ6.0AHE3/5B when AEC-Q101 compliance is not required and cost optimization is prioritized. |
| SMAJ6.0AHE3/5B | Lower 400 W PPPM; SMA (DO-214AC) package with smaller footprint and higher RθJA (140 °C/W). | Limited to lower-energy transients; less thermal margin in high-ambient environments. | Choose SMAJ6.0AHE3/5B only if board space is constrained and surge threat level is ≤400 W. |

FAQ
What is the clamping voltage of SMBJ6.0CHE3/5B at its rated peak pulse current?
The SMBJ6.0CHE3/5B clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 58.3 A (10/1000 µs waveform). This value is measured under standardized test conditions per JEDEC and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ6.0CHE3/5B maintains this clamping performance across its specified operating temperature range and after repeated surge exposures when properly mounted.
Is SMBJ6.0CHE3/5B suitable for bidirectional transient protection?
No, SMBJ6.0CHE3/5B is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the SMBJ6.0CA variant. Using SMBJ6.0CHE3/5B in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always verify polarity alignment in schematic and layout for SMBJ6.0CHE3/5B.
Does SMBJ6.0CHE3/5B meet automotive qualification standards?
Yes, SMBJ6.0CHE3/5B is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, making SMBJ6.0CHE3/5B appropriate for automotive powertrain, chassis, and body electronics where reliability under extended temperature and vibration is mandatory.
What is the maximum printed circuit board pad size recommended for SMBJ6.0CHE3/5B thermal performance?
Vishay specifies a minimum pad layout of 0.2" × 0.2" (5.0 mm × 5.0 mm) copper area per terminal for SMBJ6.0CHE3/5B to achieve its rated 600 W peak pulse power and thermal resistance values. Smaller pads reduce heat dissipation, causing premature thermal runaway during repetitive surges. The SMBJ6.0CHE3/5B datasheet Figure 2 provides derating curves based on actual pad geometry and ambient temperature.
How does the glass passivation in SMBJ6.0CHE3/5B improve long-term reliability?
The glass passivated chip junction in SMBJ6.0CHE3/5B prevents moisture ingress and metallurgical degradation at the silicon surface, stabilizing breakdown voltage (VBR) and reverse leakage (ID) over time and temperature. This directly extends service life in humid or thermally cycled environments - a key factor in automotive and industrial deployments where field failures must be minimized. The SMBJ6.0CHE3/5B retains specification compliance after 1000 hours of HTRB testing at 150 °C.
